STOVEPIPE-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 746,122, dated December 8, 1903.

Application filed November 1, 1902. Serial No. 129,726. (No model.)

-securing the end of a Stovepipe in the thimble for the purpose .of preventing the accidental displacement of the said stovepipe end; and the object of the invention is to provide a device which can be used in connection with various sizes of thim bles and stovepipes, said device being adjustable within certain limits, whereby various sizes of thimbles and pipes are accommodated;

With this object in view the invention consists, broadly, of an expanding band adapted to be arranged within the stovepipe-thimble, said band carrying a ring which is adapted to be secured to the stovepipe, preferably in advance of a ridge or corrugation formed upon the said pipe, thereby securely fastening the said pipe within the thimble;

The invention consists also in certain details of construction and novelties of combination, all of which will be fully described hereinafter, and pointed out in the claims.

In the drawings, Figure l is a perspective view showing the practical application of my invention. Fig. 2 is a longitudinal sectional View taken through the thimble and the end section of the stovepipe. Fig. '3 is a longitudinal sectional view looking-in the opposite direction and more clearly illustrating the fas-' tening device. Fig. lis a detail perspective View of the essentialfeatures of the invention. Fig. 5 is a detail perspective view of the wedge-guide which is attached to the interior of the thimble.

In carrying out my invention I employ a metallic thimble A, the edges A"being turned over to securely fasten the thimble within the opening. 3

B indicates the end section of the Stovepipe, the fluted or corrugated end B of whichenters the thimble, and it is for this purpose of securing said end within the thimble that I 'have devised my present form of fastener,

which comprises a sheet-metal band 0, divided at O, the ends being preferably cut slightly upon the bias,'said ends being adapted to engage the guideways D of the wedgeguide plate D, which is securely riveted within the thimble.

tice I prefer to have said pipe formed withan ann ular crimp or corrugation B ,and whenever said annular crimp or corrugation is present the ring F is arranged in advance of the same, as most clearly shownin Fig. 2.

In operation the band C is inserted within the thimble and the ends of said band brought into engagement with the wedge-plate D, and by pulling outwardly upon the said bandit is expanded, so as to bind tightly within the thimble. The end of the stovepipe is then inserted into the thimble and within the band.

and ring and the bolt and not are then applied, for the purpose of binding the ring socurely around the Stovepipe-section. After all the parts have been thus connected it will be impossible forthe stovepipe-section to become disconnected from the thimble.

' Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. A Stovepipe-fastenercomprising a band having arms connected thereto, a ring carried by said arms, means for contracting said ring, a thimble within which the band is 10- cated' and means connected to said thimble for the purpose of expanding the band, as specified.

2. A stovepipe-band comprising a thimble having a wedge-shaped guide-plate secured thereto, a bandarranged within the thimble, the ends of which are adapted to engage the guiding edges with the wedge-plate, arms connected to said band, a ring carried by said arms and having eyes at its ends, and abolt and nut for contracting said ring, for the purpose specified.
